      DescriptionIsopore Membrane Filter
      Background InformationThe Isopore™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore™ membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Matched-weight filters are not usually required because of low, constant tar and ash weights.

      Features & Benefits:
      •Membrane structure retains particles on the surface, simplifying counting and analysis
      •Isopore™ membranes do not stain, resulting in low background interference
      •Non-hygroscopic, allowing for rapid drying and reduced sample analysis time
      •Translucent material does not require clearing for transmitted light microscopy; also available in brown variety

      Applications:
      Air Monitoring, Epifluorescent Microscopy, Chemotaxis Assays
